PURPOSE OF REVIEW: Tuberous sclerosis complex (TSC) and neurofibromatosis (NF) are neurocutaneous disorders often encountered by neurologists in clinical practice. This article aims to familiarize adult and pediatric neurologists with common features of these disorders and headache specific evaluation and management.
RECENT FINDINGS: Non-malignant intracranial tumors in TSC include cortical tubers (glioneuronal hamartomas), subependymal nodules or subependymal giant-cell astrocytomas (SEGA). Headache disorders in TSC are largely secondary and can cause headaches due to increased intracranial pressure, mass effect, obstructive hydrocephalus, or hemorrhage. Neurosurgical intervention is typically required for management of large SEGAs; however, in patients with increased surgical risk, newer treatment modalities may be offered such as neoadjuvant therapy with an mTOR inhibitor (mTORi). Newer studies indicate headache disorders are more prevalent in neurofibromatosis type 1 (NF1). Primary headache disorders can include migraine and tension-type headache, while secondary headache disorders can be due to associated neoplasms such as optic pathway gliomas or brainstem gliomas, or less commonly vasculopathies such as moyamoya syndrome. Selumetinib is an oral, small molecule mitogen-activated protein kinase (MEK) agent with antineoplastic activity which is in ongoing trials for treatment of NF1-associated pediatric low-grade gliomas. NF1 stands out as having a higher association with primary headache disorders such as migraine. This association may be related to effects of mutation of the neurofibromin gene on pathways involved in pain and migraine genesis, however, warrants future study. Care should be taken when formulating a headache treatment plan to address comorbidities and avoid medications that may be contraindicated.
